Factors affecting common lambsquarters' tolerance to imazethapyr
… conducted to examine the tolerance mechanisms of common lambsquarters (Chenopodium album) to imazethapyr (2- (4,5-dihydro-4-methyl-(1-methylethyl)-5-oxo-1H-imidazol-2-yl) -5-ethyl-3-pyridinecarboxylic acid, active ingredient of Pursuit$\sp\circler$ herbicide) by comparing it with susceptible …

Differential Response of a Virginia Common Lambsquarters (Chenopodium album) Collection to Glyphosate
The purpose of this research was to evaluate a common lambsquarters (Chenopodium album) collection from Westmoreland County, Virginia, which exhibited a differential response to glyphosate treatments as compared to most other common lambsquarters. Plants from this site that survived glyphosate …

The Role Of Soil Microorganisms In The Resistance Of Giant Ragweed, Horseweed, And Common Lambsquarters To Glyphosate
… horseweed [(Conyza canadensis (L.) Cronq.], and common lambsquarters (Chenopodium album L.). Through a series of greenhouse and lab experiments we determined that root colonization by soil microorganisms increased the activity of glyphosate in glyphosate-resistant (GR)</p> <p>and -susceptible …

The isolation and characterization of common lambsquarters cuticles and the effect neodol surfactants on the penetration of bentazon and glyphosate
… a microlepidopteran leaf miner. Cuticles of common lambsquarters (Chenopodium album L.) were isolated by the leaf miner technique. Electron micrographs verified the successful isolation of leaf cuticles, which include epidermal cells, without structural alterations of the adaxial and abaxial …

Triazine resistance in Chenopodium album and Amaranthus hybridus in Virginia
… distribution of s-triazine resistant biotypes of common lambsquarters (Chenopodium album L.) and smooth pigweed (Amaranthus hybridus L.) in Virginia. Collections of seed were made from suspected triazine-resistant biotypes of common lambsquarters and smooth pigweed from counties in Virginia which …

Investigations on the Interations of Acetolactate Synthase (ALS)-Inhibiting Herbicides with Growth Regulator and non ALS-Inhibiting Herbicides in Corn (Zea mays) and Selected Weeds
Herbicide combinations are common in corn production in the United States to control broadleaf and grass weed species. Studies were conducted in 1995 and 1996 to: (1) investigate the interactions of 2,4-D and dicamba with halosulfuron-methyl on common lambsquarters and common ragweed control in …

Incorporating the Experimental Herbicide CGA 362622 into Cotton Weed Management Programs in Virginia
… Timely applications of CGA 362622 controlled common ragweed (Ambrosia artemisiifolia L.), common lambsquarters (Chenopodium album L.), annual morningglory species (Ipomoea spp.), and common cocklebur (Xanthium strumarium L.). However, CGA 362622 applications generally did not control spurred …

Effect of Temperature and Chemical Additives on the Efficacy of the Herbicides Glufosinate and Glyphosate in Weed Management of Liberty-Link and Roundup-Ready Soybeans
… on the transgenic soybeans. Three annual weeds: common lambsquarters, giant foxtail, sicklepod, as well as two perennial weeds: common milkweed and horsenettle were included in studies. Uptake, translocation, and metabolism of 14C-glufosinate + AMS or PA, were studied in the five weeds in order …

Evaluation of CGA-136872 and DPX-V9360 for postemergence use in corn
… Pers.), giant foxtail (Setaria faberi Herr.), common lambsquarters (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.), particularly with early applications. However, johnsongrass rhizome regrowth prevented full season control of this species with early postemergence …

Weed Management Programs in Potato, Transplanted Tomato and Transplanted Pepper with Rimsulfuron and Other Herbicides
… were investigated during 1992, 1993, and 1994. Common ragweed control by PRE combinations of metolachlor with linuron or metribuzin was higher when treatments included PRE or POST rimsulfuron. Common lambsquarters control was 93 to 96% by treatments that included POST rimsulfuron. Applications …

Herbicide-based Weed Management Systems for Potato (<i>Solanum tuberosum</i>) and Wheat (<i>Triticum aestivum</i>) and Growth and Reproductive Characteristics of Smooth Pigweed (<i>Amaranthus hybridus</i>)
… to foliage. Sulfentrazone effectively controlled common lambsquarters (<i>Chenopodium album</i> L.) at rates as low as 0.11 kg/ha and also controlled several annual grasses at higher application rates, but was slightly less effective on jimsonweed (<i>Datura stramonium</i> L.) and ineffective on …

Herbicide evaluation for broadleaf weed control in direct-seeded broccoli
… 0.56 kg ai/ha provided excellent control of common ragweed with little or no visible crop injury. Common ragweed control with oxyfluorfen varied with soil moisture and organic matter. Applications of 0.28 and 0.56 kg/ha oxyfluorfen significantly reduced yield when compared to the cultivated …

Studies on the Nature of Triazine Resistance in Weeds
Triazine susceptible and resistant common lambsquarters (Chenopodium album L.) were grown under non-competitive conditions in a growth chamber. Although the two biotypes had equal leaf areas on a per plant basis, dry matter accumulation at pollination was 9% and 20% less in the resistant plants …

Field, greenhouse, and laboratory evaluation of the efficacy and selectivity of the herbicide thifensulfuron for weed control in soybeans (Glycine max)
… was required to obtain consistent seedling common lambsquarters (Chenopodium album L. #CHEAL) control. Chlorimuron and thifensulfuron combinations did not control ivyleaf morningglory [Ipomoea hederacea (L.) Jacq. #IPOHE]. Greenhouse studies evaluated soybean cultivar sensitivity to …

Composted dairy manure and arbuscular mycorrhizae influence on weed competition and potato yield
… weed-free conditions, and in competition with common lambsquarters (CHEAL), giant foxtail (SETFA), and hairy nightshade (SOLSA). In the fall, one hundred seeds of each weed species from each of the composted field plots were buried to a 5-cm depth in the weed-free plots of each compost rate to …

Evaluation of integrated weed management techniques and their nuances in Virginia crop production
… weed species, four broadleaf (redroot pigweed, common ragweed, common lambsquarters, and common cocklebur) and two grass species (large crabgrass and giant foxtail). Results indicate that among summer annuals, broadleaf species retain larger proportions of their seed compared to grass species at …

Optimizing Foramsulfuron for Weed Control and Corn Tolerance
… treatment of nicosulfuron. However, control of common cocklebur, velvetleaf, and common lambsquarters with foramsulfuron was superior to nicosulfuron. Tank-mixtures with atrazine antagonized giant foxtail and fall panicum control, however improved control of several broadleaf species. This …
